Railfan Technology > Posting a video test

I watched #3 make a reverse move into the Riverside depot this morning. They used the air wistle and I thought it would be interesting to post a video. With no idea how to post videos from my phone, I kept punching buttons until I got this far. Seems pretty jerky when I view it here on TO, probably doing something wrong. Suggestions welcome.

Played smooth for me after one hiccup right at the beginning.

Good video

Nice Searchlights!

You did good.

Excellent video, audio, and pan, thanks.

I do get some stuttering when watching the video, but that's no different from most other videos I've viewed on TO.  Probably something to do with my connection or hardware rather than the videos themselves.

Nice to see a slow 'roll-by' from track level.
That whistle is a real 'Pip-Squeek' !

Good job, and thanks,

Great video, nice quality! Hope you post videos more often.

The video played as smooth as others here on TO, occasional jerkiness. I downloaded your video to play it locally on my machine, and it plays smoother. That points to the combination of your video's bandwidth, TO's browser-hosted video player, and user's computer's hardware capability as the cause of jerkiness.

Before I upload my videos, I usually reduce the video bandwidth ahead of time, sacrificing resolution (854x480, DVD quality) for smoothness. TO will still "post-process" my video, so the video bandwidth is usually half of what I uploaded, for example 6 Mbps to 3 Mbps. I noticed you uploaded yours at HD (1920x1080), and the video bandwidth ended up being around 4 Mbps. That should be OK for most people.

I played the downloaded video on different machines I have, and I noticed the "same" jerkiness, which possibly points to TO's software, but this should be minor, so I wouldn't worry about it. It is kind of a hassle to downgrade the video resolution and bandwidth before you upload, usually requiring a video editor or a filter software, but that's the most effective way to reduce jerkiness. That's based on some tests I did several years ago to try to make my videos more friendly to Mac users, who complained the videos played jerky.

Thank you Charles and others, I have cell phone videos from the last several years that need editing, mostly because of lots of dead time in the beginning. I have one in particular in mind that I think many would enjoy. I'll have to play around with it one of these evenings when I'm bored.

I videoed the Big Boy last October using my Android phone, only railroad filming I've actually done in a long time.

My video setting was at Ultra HD, which creates a huge file size.
There's also Full HD, then HD settings on my phone.

Full HD seems to be a happy medium for me, which creates a smaller, but still a huge file.

Then there's just HD, which will create the smallest HD video file

My Ultra HD 5 minute clips were way too high a MB count to upload to TO or any other site (remember TO limit is about 410MB) and it just kept cycling when trying to upload, then I realized I had to reduce the clips to regular HD, and they uploaded just fine.
