Re: Quicktime : the dying and abandonned file format

I always export to image sequences, but I need to import a lot of .mov files...

I might be wrong, but if the premultiply and no-premultiply options are used as they should, there is no problem with PNG.the png export in TVPaint is absolutely fine if you don't need an alpha-channel, but if you need one it never looks the way it should.
Even in the lastest 10.5.7 ? If so, just do the above mentionned : open a new topic about it.And I always got the problem that in nearly every sequence I rendered, exported whatever at least two images were missing.
Once again, the internal AVI works on almost all players including the ones on Mac.Unfortunately AVI isn't a format which you can expect much support for on an computer running OSX, as far as I know.
I tried to reproduce the bug, which always happened to the edges, no matter if I choose premultiply or no-premultiply, but the png with no-premultiply was absolutely fine.Fabrice wrote:hello schwarzgrau,

If you think there is a bug, just open a topic about it, we will have a closer look together.
This shouldn't be an insult against TVPaint, more something like a general problem I got with PNG sequences, mostly from AfterEffects.Fabrice wrote:Even in the lastest 10.5.7 ?

I gave it a first try and I must confess it looked better than expected and I can import it everywhere.Fabrice wrote:Once again, the internal AVI works on almost all players including the ones on Mac.
I was created by TVPaint to works on all platform (like Android were nobody can expect to use QT in the future) ... so we can debug, improve and support it easily.
No worries, I didn't take it as an insultThis shouldn't be an insult against TVPaint, more something like a general problem I got with PNG sequences, mostly from AfterEffects.
Premultiplied alpha isn't really supported in the PNG format, to emphasize this in the last build you should have a warning if you select premultiplied PNG.schwarzgrau wrote:Sorry It seems I always choosed premultiply, since there you can see this transparency checkerboard background.
We tried to find a quick and easy solution : there is not.
The only way to use a third-party 32 bit application when working with Quicktime is to spend months (no documents, no financial support and a 5-developers team = many months) just dedicated to THAT development, without being sure of future Apple policy! Honestly, it isn't worth it, sorry. There are much more interesting and important things to do in TVPaint.![]()
Trust me, for film editing, image sequences in PNG are MUCH better than Quicktime files. And for final exports, AVI does exactly the same job. If other users and companies can do it, why can't you ?
An era is slowly coming to the end because Apple decided so : the faster you will accept it, the faster you will change your habits.
I had to read it to believe someone wrote that ...The colours are worse compared a high quality quicktime
As far as I know, our internal AVI is supported by both VLC and Quicktime player on Macs/Windows/Linux and doesn't require codecs to be installed. If not, we should be able to fix it.Avi is also not a good alternative. It's not supported for every other software for mac, and even the persons in my studio with a Windows computer prefer Quicktime.
Often images get corrupted or get lost completely after an export/render. The failure factor is just naturally higher if you work with hundreds of files, than only with one video file. As is wrote it has it's PROs, but even more CONTRAs, especially for the every day use.Fabrice wrote:No worries, I didn't take it as an insultThis shouldn't be an insult against TVPaint, more something like a general problem I got with PNG sequences, mostly from AfterEffects.but maybe misunderstood : the two missing images you mention are occuring when you play the animation in quicktime ? or when exporting with TVPaint / AE / etc ...?
Yea, there was this warning. A good idea by the way. But maybe you could add the checkerboard-background to the preview of NOT PREMULTIPLIED. I guess a lot of people get confused like me if some option has this transparency-checkerboard and the other option hasn't it, but would be the right choice.ematecki wrote:Premultiplied alpha isn't really supported in the PNG format, to emphasize this in the last build you should have a warning if you select premultiplied PNG.schwarzgrau wrote:Sorry It seems I always choosed premultiply, since there you can see this transparency checkerboard background.
