I have a general question I would like to ask about the differences between Krita recorder and other app use for recording a timelapse. I mainly want to know about their storage usage, I already did a painting in 7680x3398 and recorded a timelapse using krita recorder it works really well, I exported it and resizing to 1024x1024 and it seems blurry when upload to youtube. What size should I export it as and if the size kept increasing does Krita recorder still use less space or more than other methods?
If someone have experience in this please let me know. Thank you in advance!
I’ve never used OBS so my comments refer to ways to make the best use of the recorder docker in krita.
The amount of space that a timelapse folder takes depends on the settings in your recorder docker.
I change the interval to 20 or 30 seconds as I don’t like long timelapse recordings. If you leave yours on the default of one second, or worse yet if you set it to record continuously, you’ll eat more storage space.
The canvas size you mentioned is way too large to record at 100%. I usually set mine to half and I reduce the quality to 80% and I use jpeg.
When it comes time to export to mp4, use the resize button but not the way you have stated. Changing your canvas size to 1024 x 1024 is going to skew the results terribly because your canvas is a rectangle but you have chosen to resize it to a square. And YouTube is probably going to expand that up to its normal 1920 pixels which will blur your image (I think).
I meant resizing in the export option i changed it to square but it seems the proportion of the picture in the video still the same, I tried export in 1920x1080 and it seems to have higher quality. Also I don’t know if it shows correctly but the size and size on disk for that 18mins vid file somehow only 19 MiB?
Yes when you have the time lapse in just 1/7th the original artwork’s size you will lose quality (since you throw away pixels) doesn’t really matter if using OBS or Krita’s recorder docker. The difference is that OBS can at best record in your display resolution while Krita can record in the artwork resolution if you really wanted to but files get huge, a lot of storage is needed, rendering takes a lot of memory and at the end you probably have to downscale to a sensible resolution anyway when you want to share it so there’s no point in having a huge recording resolution most of the time. What OBS can do what Krita won’t is being able to record the whole interface, which can be useful in some cases (like recording tutorials where you usually want to show all mouse movements and tool usage).
OBS also records the strokes as you make them, rather than just a snapshot between strokes, and it records your view rather than the entire piece, so people can see what part you have in view, what tool you’re using, etc. It makes a completely different kind of recording than Krita’s recorder, and I think that difference in kind should be the primary factor to consider.
If you want a short-form result, use Krita’s recorder, because a screen recording (e.g. OBS) will have too much movement to be legible or pleasant once sped up so much, and the extra details of the recording won’t be noticeable anyway. For a long-form video that isn’t sped up so much, a screen is better because it’ll focus on the relevant parts of the canvas and better show the process. There’s no exact boundary where one is more appropriate than the other, it depends on your style of working and your desired presentation style.
It’s not unusual for a video without a huge amount changing each frame to be small. Since a Krita recording is of the whole canvas but each frame usually only has a change in one tiny part of it, that can be compressed efficiently because most of the frame is the same as the previous frame. OBS recordings will tend to be larger because moving around the canvas will mean more of the video frame changes, though they can still be surprisingly small.
I use OBS to record my paintings. I have it set to record my Krita window and my cam positioned by my tablet to be able to see me actually drawing all at the same time. The file size is usually pretty reasonable. I also take that file load into my video editor and make cuts and add music to upload to YouTube.
As for the Krita recorder I’ve only used it a few times and thought it was great for what it does it just didn’t do the things I needed for uploading.
Each have a use case it all just would depend on what your wants and needs are.
