Reclock and live TV (1 Viewer)

[esas]

Is it possible to use reclock with live tv. I've been trying for a while now with no luck, so I guess it's not.

My problem is that my monitor/TV only supports 60Hz (in 1360x768) and all my live tv signals are 25 Hz.

To get reclock do its magic you would be needing a way to travel in the time I.e. reclock would speed up the playback approx 10% but there is no possibility for that as the broadcaster is not sending the data any faster.

Thanks! That was my thoughts ass well. If I rewind live TV 15 seconds the picture is fine untill the recording catches up with live TV again.

Is there any other smart methods to get smooth playback on live TV with 25 fps on 60Hz display?

No.

Short and simple answer.. Hmm.. Anyone interested in a Sony 40D3000 then? Guess I have to buy myself a new TV.

This TV supports other resolutions surely? My sony does 1280x720@50HZ, not 1 to 1 pixel mapping but with video its not really necessary.

There is another way to get smooth playback but it's very tricky and requires a lot of resources. It's called motion compensation and you can use it with ffdshow as codec and an avisynth script. Look at this thread : Avisynth Script for doubling video frame rates - AVS Forum

How it works: It inserts missing frames depending on the motion vectors of the frames around. The same way modern lcds and beamers double their framerate. But be aware that this is not perfect (neither the script nor the lcd technology). Especially in fast scenes you sometimes get wrong frames and when you set the overall framerate high (ie. 60fps) your movies look like soap operas, but they are extremely smooth.

I'm watching PAL television material with 50 Hz TV. Also with this setup and reclock the result is not good with live TV - sometimes the lip sync gets terrible. Is there any chance to get live TV without any dropped frames?

Live tv works on my HTPC without dropped frames So yes it is possible, but hard to say what is source for the dropped frames / stuttering on some specific systems.

Reclock isn't designed to work with livetv and most likely channel changes are confusing it's internal logic and cause lip sync errors or even stuttering. So Reclock shouldn't be used for live tv.

Are you really positive that your system never drops a frame, or could it be possible that you are one of the fortunate who doesn't see this? If you watch a news ticker for a minute, does it go completely smooth all the time? I just don't undestand how perfect playback would be possible without using Reclock.

For example in my setup, MediaPortal always claims zero dropped frames, but during pans, news tickers or scrolling credits there is a very brief "jump" once in three to five seconds.
