TIFF export

[regenbot]

I'm having trouble exporting Tiff sequence. It just exports one image. jpg sequence works fine.

Is it broken? Or am i stupid.

Win 7 64bit
TVPaint Pro 10.5.4 64bit

Cheers, Heikki

I'm on a Mac I don't have any problem here.

But why are you using TIFF ? it's an heavy file format, you should better use PNG

[regenbot]

Mainly because my educators adviced on using tiff, I'll use PNG for now then.
But sure would be nice to get the tiff expoting to work too

Your educators need re-educating. TIFF is for print; JPEG or PNG for video.

Isn't there a risk of quality degrading if you pack the image. I mean if you export it to JPEG and do some work on After Effects and the again export to JPEG it bound to look like crap eventually? no?

With JPEG, yes, because it is a lossy compression.
With PNG, no, it is a lossless compression.
That's also why compressed PNGs are bigger than compressed JPEGs, they have to keep all the information while JPEGs throws away all details up to a certain "size".

Ok, nice i'll have to try to educate my educators then : )

But aren't JPEGS better for certain conditions and PNGs for other ones? I use JPEGs for video sequences that aren't intended to be further worked upon and they play better in an NLE than PNGs. I see no difference in the quality of the imagery, except for the better quality of playback speed in the editing process.

Of course, if just the creation of an AVI is not the final destination than PNGs should be the choice. Am I mistaken? Would I be better off using PNG sequences rather than JPEG AVIs even if I am not planning on doing anythnig else than having my project converted to one of those e-book proprietary formats I know nothing about yet (but should start learning)?

PNG/QT with PNG is my format of choice as long as I haven't done anything final for distribution. I never know when a client asks for some printable stills, or I need something to use it in another project again. So all my inhouse files are best quality all the time, and only stuff which goes outside is compressed.

[ematecki]

JPEG is intended for final output, not for further processing.

So if you will never change the JPEGs again (like for preview in your NLE), it's OK.

For converting to mp4 (that ebook format), if you don't compress your JPEGs too much, I guess it's OK...
But be sure to try with your most detailed scene and several JPEG compression values before converting the whole project !

With Tulip I had to convert my AVIs to PNG sequences for the purposes of filmmout (35 mm film) where the lab scans individual digital frames to individual film frames. Do you know if the process to e-books also involves such scanning technology? Could you perhaps point me to a reliable source of information where I could read up on this technology?

[ematecki]

It is essentially selecting the right codecs with the right parameters in the NLE before exporting.
So any file loadable by the LNE should be fine.

But because of DRMs, there are some additional steps involved, and my knowledge stops there...
This may or may not happen in another app than the NLE.

Heikki, it seems the exportee needs some zeroes in the end. For example, "example000" should export the tiff sequence.

But, PNG sounds like the way to go from now on.

Basically JPEGs are only good for internet, or storing Photos for viewing, not really for any video or animation work. But then again - you refer to JPEG AVI, which is not the same as JPG image sequence... I wouldn't use any of these for any final product. Of course JPG with very high quality setting would produce almost a losless image, but then it loses it's size benefit - then just use PNG anyway.
e-books normally use a lower quality format video, than TV or Cinema , so that should be of less concern, but there are limitations, which depend a lot on a destined device (ipad, android, kindle, etc.) so this should be checked by a developer.

I never realized this but of course it does make sense now that you say it and this is the format I am heading for.
