Anyone doing Super 8 conversions?

PeterWright wrote on 6/28/2023, 11:27 PM

I've just acquired a machine which converts Super 8 Cine to MP4 at 1440 x 1080

The original film was 18 fps, and the MP4 which the machine produces is 30 fps.

So far the footage looks ok but playback is jittery. I'm trying different settings, but if anyone has already grappled with this process I'd love to hear any experiences or tips once the MP4s are on the Vegas timeline.

Thanks.

I guess it just run the film and not scan the frames

One tip I've found - The speed seems a little fast, so I've Ctrl/dragged to reduce speed, but because there's no audio event. Vegas doesn't tell you the percentage.

Solution - put any audio underneath and Select both video and audio /G to group.

The audio now tells you the percentage - once you've finished, you can discard the audio.

Rightclick the event and check properties, there you can change the playbackrate. Example 0,750 stands for 75%. No need to add audio.

Thanks 3POINT. 0,6 does the trick converting 30 fps to 18.

What machine? I have a RetroScan Universal from Movie Stuff .. it does frame by frame scanning of the Super 8mm so there is no specific frame rate. I then open that file in Vegas as an Image Sequence and render to 30 fps for frame rate. I could render to 18fps but Media players don't necessarily playback at 18fps. It's been a long time since I used the Retroscan so my memory could be fogy. I think my Super 8mm camera did do 18fps when shooting. My Super8mm project goes at that framer rate but do Media Players like VLC or Windows Media Player?

Is @johnmeyer still around? Back in the day, he was the master of film conversions.

Hi xberk.

It doesn't seem to have a name, just Movie Digitiser. It's made, of course, in China and I have seen the same basic machine marketed under a few different names.

Anyway, this one scans at 2 frames per second, but instead of outputting an image sequence it converts straight to mp4, 1440 x 1080 at 30 fps. As mentioned above, changing playback rate tp 0.6 reduces motion to normal speed.

I'm still not sure about aspect ratio - it comes up as widescreen, which the Super 8 wasn't, and I'm still trying to work out if it crops the top and bottom or stretches - some family members appear slightly stouter than I remember!

Might be a setting you can change, this guy may have the same unit as you his 8mm (not super8) looks to have correct ratio

@PeterWright 1440x1080 is 4:3, the correct aspect ratio. If it's looking widescreen or cropped then something is wrong.

I've just remembered Vegas in posts a few years back had problems with 1440x1080 and wrongly assumed it was HDV and stretched it. Go into the files properties and alter the pixel size or aspect ratio to quare 1:1. The problem may have been fixed in recent versions. You don't say which VP you are using.

Thanks Eric
I changed the Pixel Ratio to 1:1 in Project Properties, which made it look right again. Changing in the event's File properties didn't seem to change anything. I'm using V19 Pro
