What to do with timelines (way) bigger than original videos?

I am working on a project with 10 episodes, which are all MKV files with a total of 2,76 GB. Adobe Encore doesn't recognize MKV so I've used Handbrake to get MP4 files. Those are smaller and there's a total of 1,29 GB now. So you would say that there's enough free space on that disc, but sadly enough it's encoding when I put those video files in timelines. All are less than 150 mb but as a timeline it's suddenly 420 mb each. I'm really confused, because it seems that it's focussing on the time length of the episodes, which are all the same. Everything adds up to 4,33 GB now so I don't have any free space left for extra content like trailers.

So the question here is, why does Adobe Ecore want to make those timelines bigger and how can I avoid this? Do I perhaps need to transcode the files in AE and if that's the case, what settings do I need? The framesize of the videos is 720x480 and the FPS is 23,98. In AE I'm using settings for a PAL dvd.

Thank you in advance,

Thijs

Thank your for your answer, Jeff.

It's indeed a TV series, but it's an old anime (1998), taken from old VHS tapes. The quality is remarkably good, but it's definitely not HD. I'm working on projects to have a bookshelf of touchable nostalgia, so creating these dvd's is fun and for nostalgia reasons. I'm making some nice motion menus and dvd covers for it.

That aside, the length of the videos is 24:36 and there's a total of 28 episodes. I wanted to burn three dvd's, but now I want to put 7 episodes on each disc, so there will be four discs. That would be ~3 hours per disc, which exceeds your 2 hours of video statement by an hour. So I should probably be doing 4 or 5 episodes, but I don't think the quality will suffer that much. I can be wrong of course, I'm just a beginner with this kind of stuff.


Since the video is anime, it is possible that it could look acceptable at 7 episodes per disc. The more video that you put on a single DVD, the more it must be compressed of course to fit. However, since it is a "cartoon" format which I presume will have far less detail than actual video content, it could conceivably handle the extra compression better than "video" would. Your content may also have static background a lot of the time where just the characters move a bit, again allowing for lower compression.

I would simply put maybe 5 minutes of clips on a Premiere timeline, representing a variety of shots from your videos. Then Export using MPEG-2 DVD format. You will also have to choose a preset then, such as DV NTSC or PAL NTSC depending on source footage and your location.

I would encode using 2-Pass VBR (Variable Bit Rate) encoding, at a rate of 3.0mbps for 7 episodes, which is nearly 3 hours of material. You can set Min 2, Avg 3, and Max 5 for instance.

This will export separate audio and video clips as .wav and .m2v files, which is how Adobe Encore likes it. Import those clips into Encore, then Author and Burn a sample DVD, and watch it on a home TV set from a set-top DVD player. I never recommend using the computer to test/preview DVDs since the playback quality can vary wildly due to software DVD player being used. Previewing in a "home viewing setup" will more truly represent the end result.

Thanks

I don't do that process, but I **think** you are working with HIGHLY compressed files that are then being transcoded to the DVD specification, which is not as highly compressed so the files are larger

And, yes, Encore doesn't look at the file size, it looks at the video length

Thank you for your answer.

The original files might be compressed and converting to MP4 compressed those files even more. So that means Encore doesn't accept the fact that it's compressed and just increases the size again, or something like that. II just want to keep the quality and the right amount of free space, but it seems like that's not possible with 10 episodes.

I have a total of 27 episodes and a movie, but I think I could burn three discs for the series and one for the movie. Dvd's are very cheap, so it's okay I guess. That's one option. The other option is to change the transcode settings to FLV, that makes the files smaller. I'm not sure, but I think that won't do the quality any good.

Any other suggestions or are those my best options?

"Lines in the preview" - I wonder if that is interlacing you are seeing? Maybe need to deinterlace, OR - maintain interlacing from source to DVD.  Would you have a short sample of the .mp4 you could make available for testing perhaps? Hard to make judgments on these things without seeing the footage to understand what you are seeing there.


Thanks

Original .MKV file

Converted .MP4 file

I was away for a few days, so I couldn't send the videos. Making short samples of it would probably result in a different conversion, so I thought it would be best to just upload the whole video files. And yes, interlacing is what I meant!

Thanks
