Burning Blu-Ray issues.

chris-p wrote on 10/22/2016, 8:11 AM

Can anybody help please? When I save a 1080p file in Movie Studio Platinum 13, rendering a mpeg2 to burn onto blu ray, I review the file in Sony Architect, and it's not as sharp and vibrant as the mpeg4 version which I always render for my usb stick to plug into my tv to check the final edit.

On my pc the mpeg4 looks perfect as well as my tv. I check the mpeg2 file properties once in Architect, and although I did render it as 1080p 16bit, in Architect I have to change the setting from standard hd to full hd before burning. Once I have burned the blu ray, not only is the quality less than the mpeg4 verson as I mentioned, but it plays jerky, especially when there is movement, like panning, and people moving around. Could this be missing frames? Does anybody recognise this problem, and can point out what is going wrong? I'm lost on this.

I can't see any difference in my settings before rendering, apart from one is mpeg4 for my pc and usb stick, and one is mpeg2 for blu ray. Thanks.

Chris.

Are you converting it to 1080i for the Bluray?  1080p is not a bluray supported format.

Thanks I will have a look at that in the week when I'm off work. I did forget to mention that when I play the mpeg2 in Architect before burning, although the quality is not as good as the mpeg4 version, it doesnt seem to stagger in places like on the actual disc playback. I forgot to mention also, the mpeg4 is 25f progressive, but when I tried rendering the mpeg2 25f it had to be interlace which looked terrible. So I tried rendering 24f progressive, which solved that problem, which was jaggid and swerling looking. That's gone, so it's just the lack of sharpness and vibrance, and the staggering in places.

Anyway, thanks again, I will look at what you mentioned. You can probably tell I'm a novice at this.

Is your source material 1080 50p?  If so you need to export as a Blu-ray 1080 50i file for DVD Architect Studio.  As David mentioned 1080p isn't part of the Bu-ray specs although I believe AVCHD 50/60p now is. 

Personally I prefer the Sony AVC templates to the Main Concept mpeg2 ones.

Thanks. Before this last go at it, I rendered for the blu ray at 1080 25i as the frame rate is 25f. But being interlace, it looked terrible. This is why I tried rendering at 24f progressive. That jerking effect as though frames are missing, still happened beforehand when I rendered at 25i. 

In the week when I'm off work, I will try again with the Sony template. Thanks again. I will keep you posted on here.

Are you watching the 25i on a TV or computer? It should look fine on a TV.

Hello. Both tv and computer, I knew the format is meant for tv, so reserved judgement until I checked it on that. I tried it on my brother's tv too. My tv is a Samsung and my brother's is an LG. This last try at 24f progressive is an improvement on the 25i when watching on a tv, though not beautiful like the mpeg4 on my usb stick, but the staggering/jerking makes it unwatchable. Just can't watch it, so really need to get to thls. Thanks.

I am not sure I understand fully your workflow. I think you are saying your source material is 1080 50p. Then you pull it into Vegas, do whatever editing you need to do, and then create a MPEG2 that is also 1080, but 50i. What bitrate is the MPEG2 file? You can use the free MediaInfo program to find out what actually was produced.

In general you should not allow DVDA to re-render the video. Vegas will do a much better job.

Also, if the mp4 and mpeg2 are at the same bitrate, the mp4 will always look better because its compression is more sophisticated.

Actually I have rethought my last sentence in the post above. If the bitrates are the same, the mp4 will be smaller than the mpeg2 file. It should look about the same.
