Don’t use Match Source, that will literally try as best as possible to match the format of the source video.

Try using H.264 > YouTube 1080p29.97

I’m not sure what the actual problem is…where are you viewing this that you see the interlacing? And how do you intend to deliver?

I’ve been working with 1080i clips almost exclusively for many years. I edit in a 1080i Sequence in Premiere, and when exporting for the web, choose H.264 > 1080p29.97 or 720p29.97, end of story. Nothing to interpret or deinterlace, happens on export.

1080i is always Upper Field First, never change that to lower.

Hi Allison,

The issue with HDV is that it uses non-square pixels with 1.333 aspect. If you export that same way, 1440×1080 with 1.333 PAR, most software players will not respect the PAR and will assume square pixels and then your 16:9 video suddenly looks like 4:3 on playback. HDV is called anamorphic HD.

I would either go with full HD at 1920×1080 (1.0 PAR) or go down to 720p (1280×720, 1.0). Then your deliverables will always look right.

You can export MPEG-2 DVD at 23.976 frame rate, why change it?

When reading between the lines, seems like your “HD 59.94” footage is 720p then? In that case, since you are also wanting to export as 720p, the sequence should be 720p. Reason being that if you put 720p in a 1080p sequence, that 720p footage is upscaled to 1080p and loses some quality/sharpness. So then when you later take it back down to 720p during export, it no longer looks as good as it started out due to up and down-size conversions.

Create a 720p30 (29.97) sequence and edit in that. For the 1080p clips, right-click them in timeline and choose SET TO FRAME. This will make those clips fit correctly in the 720p frame, yet allows for some cropping if needed without quality loss (uses original 1920×1080 pixels when applying Motion effects of Scale and Position).

If you apply 50% speed to the 720p59.94 clips, you will have perfect slow motion with no repeat frames. I’m editing a wedding right now, source is 1080p60 and editing in a 1080p30 sequence and loving the slow-motion!!

Of course, export for your project should then be 720p30 (29.97), same as Sequence, and all is well

Hi,

I’ve seen others say that MP3 files can be an issue for Premiere, might help to first convert them to .wav 48k to match video project. Could use Audition if you have it.

Thanks

Hi Stephan,

Those render times are ridiculous. What format is the video? For instance, “AVCHD 1080p60” or whatever?

If your main effect is chroma keying, you should be able to get good results in Premiere with Ultrakey, then just export to H.264 for YouTube. Done. And it shouldn’t take more than a few minutes to render per minute of video – I have no idea where the 2 hour thing is coming from, wow. Unless there are other filters/effects you didn’t mention.

What is the actual processor model – how old is the computer? Storage can play a role – is the video on a fast,dedicated drive or is it all shared on the C: drive?

I just noticed you said you render at 25 frames. Or is it 24? You mention both. Are you in NTSC or PAL land? If footage is 29.97 and you are changing the frame rate, that can actually add a bunch of render time with the frame rate conversion, so you could be doing more harm than good with that.

Just checked specs on the GTX 710 card and that is not going to do anything for performance. It’s a $40 card. Premiere loves CUDA cores and it only has 192, with slower DDR3 memory. A real upgrade would be a minimum of something like a GTX 760, with 1192 CUDA cores and DDR5 memory. I see them still available online for just over $100. That is older tech though, current is the 10xx series, like GTX 1060. Note that these larger cards do need a suitable power supply in the PC, maybe like 450-500w or better. There is such a thing as too much GPU, depending on the rest of the system components, need to have a balance of power. That will depend on what processor model you have.

Have never used Twixtor, but an obvious difference is that most slow-motion splash videos have the camera looking at glass straight from the side, while you are shooting at a steep downward angle. And the lighting is poor. And background color is not that dissimilar from the splashing water. The glass and the water look the same to the camera/Twixtor. For instance when the rising water meets the stainless bar in background, things get a little warped because the water is the same color as the background! You need some contrast and better lighting.

And with the water rising basically towards the lens, hard for the software to calculate the motion. Shooting from the side, the background is static and only the water is moving, so software can easily determine what is moving and what’s not. When looking down on the water…well, the camera doesn’t have a 3D sensor to measure distance of water to lens so it doesn’t know what it is seeing.

Also, use a tripod. If the camera is moving, makes it harder to calculate smooth motion of subject matter.

Steps for success:

1. Camera position
2. Lighting
3. Tripod

One more thing, I’m sure there are settings in Twixtor that can be tweaked. Try the other steps for starters, then tweak as needed to get good results in Twixtor. But you have to start with better footage.

Thanks

Hi Jerry,

We need more information. What is the source? Most cameras record 16-bit audio, where are you getting 24-bit from? What’s your typical workflow?

Hi Jerry,

Mac or PC, and what is the intended use of the encoded file – meaning to put online, make a Blu-ray or DVD, put on flash drive, archive, edit?

For delivery, one would typically use H.264 because the file size are smaller, but high quality, and playable on most any device.

Thanks
