Fast 7 Preview

[Emir Ballard]

@gergio Are you using RawTherapee 5.8 or a nightly build? A change has been made since the latest release. Pressing f on your keyboard while hovering over a thumbnail in the file browser now shows a full-screen scaled preview. See Open inspector fullscreen and exploit monitor resolution, see #1474, #5591 by rfranke Pull Request #5593 Beep6581/RawTherapee GitHub

Whenever I import anything to my timeline and try to play it back it plays back probably 20-30% faster than it should. Even the timer counts the seconds way faster than it should. But if I do work on it and export it, the exported file will play at normal speed. On a maybe related note, I keep getting a message about not having enough space for the disk cache and no matter what I do it still says that... could that have anything to do with it? Should I just disable the disk cache thing? (I honestly don't know what it does) I don't know what else to say about it I couldn't find anything else about this specific problem so if you can find anything please link it to me. I am just extremely frustrated right now because it's impossible for me to properly edit anything like this.

2) What kind of camera shot the footage? I hope it wasn't a cel phone shooting at a variable frame rate. They make apps that force phones to shoot at a FIXED frame rate, which is what you need for AE.

For best results go through it step-by-step. AE is just too quirky and complicated to try to dope it out on your own... and it doesn't help that most current version comes with a huge laundry list of bugs. You don't know if a problem's operator error or software error!

This warning appears if you have the disk cache size set to greater than 80% of the available space on the drive. To make the warning go away, set the disk cache size to 80% or less of the free space on your drive, or like most of us - just click "never again" and don't bother with it. of course the exception is if you are using a system folder for a cache disk that is very low on disk space. you don't want to empty the system disk because of cache files.

We created a new Python library for Blender called 3DN BIP or 3D Ninjas Blender Image Preview. It allows blazingly fast preview loads in Blender. Furthermore, it can load preview images of arbitrary size. It operates as an bpy.utils.previews drop-in replacement and does all the heavy lifting for you.

When you load multiple preview images in the Blender UI, it can sometimes take several seconds for them to load completely. With our library, preview images are loaded in milliseconds. Developers can use the library for their addons. The library is especially appealing if you offer a selection of assets and show preview images for them.

Does it work also for regular previews in the File browser window? I mean, if I enable the addon will it help when opening a folder full of images (jpg, exr, png, tif, etc) in the file browser, say to choose a texture for a shader?

Thanks for developing this! I also with you would write a patch for Blender to use this natively. I have big libraries of textures and it would be amazing if the images were generated as fast as with your library. Great work!

Thanks for the answer but the probleme with image from render resuilt is that the image ahs no data yet.
So I guess the only solution is to save the rendering as a jpeg or png and then convert the image to .bip.

If you want to avoid being dependent on Pillow, you could use to read the rendered PNG and save BIP according to the format linked in my previous post. PyPNG might be slow, though. Be aware that you need to flip top to bottom, and you need premultiplied alpha ( -bip/blob/main/bip_converter/t3dn_bip_converter/convert.py#L33-L34).

It was both easier and more annoying than I expected it to be, but perhaps less annoying on balance than org-latex-preview locking up Emacs for a good minute on every fresh invocation in medium sized documents.

Got a small basic question. I use a Mac, and I used to work in .py files with Sublime 3. One of the things I liked was that when Sublime is closed, for a given file in a folder--if I'm looking for a bit of code--I could hit the spacebar and Macs open a quick preview of the .py document.

I suspect there are quicker ways to open .ipynb files in browser windows, but what I really want to know is is there a way to quickly preview those file contents from my desktop? Alternatively, is there a way to work in Jupiter Notebook but save the files as .py (and later seamlessly reopen in JN), such that I could still use the great old spacebar trick?

On previous versions there used to be a triangle cursor under the preview playback rate cursor setting the speed you wished the playback speed would stay every time you'd press play.
I'm trying version 17 and the triangle cursor is gone, the only option is using J or L, but the speed is reset to 1.00 every time the playback is stopped.
How can the speed be locked at a desired speed like previously ?

Thanks Marco! Do I feel silly ? yes, I tried many things before asking, except widening the panel which on the project I opened was narrow and didn't have the triangle . Widened it and there it was. Cheers !

No, you should feel silly. This is a design flaw. If the panel is reduced in size (to a "normal", acceptable width, not taking up 1/4 of the screen) then the slider should be repositioned underneath the "Rate" value so that it remains visible. I would never have thought to increase the width of the panel (substantially) to see this elusive triangle.

(Without changing frequency of course, because then the narration becomes unintelligible?)

BTW I couldn't find any preference settings to change the JKL speeds, and the preferences for JKL shuttle speed in editing (slow/medium) doesn't do anything either).

Spend some time editing on an audio reel-to-reel, Old school folks learned to edit without an option to maintain normal pitch. There was no easy 'undo' or 'redo' either. Then there was the risk of physical injury with a razor blade. (end rant)

It seems ridiculous to me that the ESPN app has no preview/viewing capability when fast forwarding or rewinding. That means if you're trying to go back or forward in a game, you're doing it totally blind. Almost every other app I use on Roku (from HBO to Hulu to Netflix to the provider apps) include this as a normal feature. And ESPN's apps on all the other platforms like Apple TV and Fire TV offer this functionality.

Please be advised that the channel developer themselves maintains channels on Roku. We suggest reaching out to the channel provider's customer support team to report the issue and get help. There's likely an issue within that specific channel that needs to be addressed with an update from them.

I posted here also to make sure that it was, in fact, a known behavior of the app and a feature that doesn't exist, rather than a technical error/issue with my own app or Roku. (ESPN's apps on every other platform have this feature, so wanted to make sure it was in fact expected to be missing from the Roku version for some reason.)

Update: Spoke to someone at ESPN, who said that this is indeed true that the ESPN app doesn't offer this functionality and that it is a "Roku device issue". So they claim that it's something about the way the Roku or its software is built that prevents them from adding this function. Not sure why that would be, but kind of leaves me stuck with the only device in the streaming world that doesn't allow the ESPN app to give a FF/REW preview. All of the other ESPN apps do.

Me and my team just recently moved from Trello to Asana but we are having a hard time with documents. We need PREVIEWS trello like, for PDF, DOCX, and PPTS. In Asana we need to download to view, it would be awesome if that file could be previewed in browser, we preview a lot everyday. we have remote workers and its better to not have lots of versions downloaded.

th the exception of the million dollar budget spots that air during the Superbowl, people generally hate watching commercials. Thankfully, about a year ago Tablo added support for Fast Forward Preview which makes it easy to quickly speed through advertisements and get back to the show you were trying to watch.

Since generating the preview thumbnails requires a tuner, if all of the tuners on your Tablo are busy with other tasks (like other recordings, live TV streams or out-of-home streams) your DVR will wait until those tasks are completed before processing the thumbnails for your recording. This is one of the many advantages of having additional tuners like the Tablo QUAD does!

When there is an available tuner, your recording should show Fast Forward Previews approximately 4 minutes after the recording has finished (for an hour-long show). Longer recordings will require additional time for processing.

Creation of Fast Forward Preview thumbnails are also completed in a serialized way. This means that if you have 4 one-hour recordings completing all at one time, it will take approximately 16 minutes for all four recordings to show previews.

While not a common occurrence, it is possible for Fast Forward Preview generation to fail. This is almost always caused by an error in the actual recording, generally resulting from a degradation in the Over-the-Air signal during the recording process.
