Watching the Angels/A's game on FOX in the Los Angeles market. Is anybody else noticing this effect on some of their cameras? Some have the normal video look to it while the main cam and a couple of others appear to have a slight stutter or almost 24p movie effect. I'm starting to think this is intentional. It was happening during the All-Star game, and another FOX Saturday game the week prior. I don't know, just kind of weird and distracting for my taste. Or maybe it's just a local issue.

I noticed the same thing on my Fox HD Comcast signal here in Northern Virginia during the All Star Game. Major stuttering effect any ideas or explanations would be helpful

I have noticed this too, and find it highly distracting.

Same here, when watching ESPN, Cubs game. Switched over to another game, forget the channel, no issues. I would say the problem is at the source, not your set.

Almost sounds like the camera shutter speed is higher than 1/60th second. Is the motion still smooth, or is a bit jerky (like 30P or 24P)?

Could they be cutting 180Hz SuperSloMo cameras up live? (They often look horrid live as they output every 1/3rd 180Hz frame - with a very short shutter setting)

No, i'm certain it has nothing to do with a higher shutter speed setting that the super slow mo cameras posess. Its on the main center field camera and has more to do with a movie like slow film non video appearance is the best way i can describe it. Kinda like what producers will apply when showing halftime/postgame montage highlights.

I noticed this on all recent Fox MLB broadcasts as well. However, when I switch to the OTA feed it seems to not happen. I'm on Comcast. Maybe it's a Comcast thing?

The effect has now spread to ESPN... I'm currently watching the Sox-Rays game on Cox HD Cable in San Diego and every camera angle has the bizarre 24p effect that I've noticed on all games on Fox since the game the OP referenced.

I found this forum after Googling randomly to try to figure out what's going on with HD MLB broadcasts this year. Glad to see I'm not the only one who's noticed it, but I'm also shocked that none of the major baseball writers have written anything about it.

I have the same problem as the original post. "Stutter" effect only on Fox MLB broadcasts from the centerfield camera. First noticed it on the All-Star game broadcast and has continued since. Watching on Comcast in Charleston, SC.

Most broadcast cameras that can handle 24p have to be configured to do so at the CCU. It's not something that can be easily done, or a switch that can be accidentally hit while on air, even on the Thomsons which are format switchable at the camera head. Furthermore the truck would likely have to be configured to handle a true 24fps signal, or introduce some sort of pulldown from 30i or 60p. It's also highly unlikely people in the truck wouldn't notice this, or the camera op for that matter. I would almost chalk the choppiness up to a 1/30 shutter if it was just one camera and not across networks.

Because its happening everywhere though, makes me wonder if a headend somewhere is introducing a pulldown. It's also strange that you would only see it one camera and not an entire broadcast.

ABC, I'd be interested to know if this is an issue with a local affiliate's splicer.

now I'm really curious to see this effect. Will be watching for it next week. Anyone have a sample? We can step through the frames to determine the cadence

Yes, I saw it this evening during the football game. I'm guessing this has something to do with the splicer upgrade perhaps. It's uncomfortable for my viewing. I'm curious to see the highlights of it on Sportscenter this evening and whether or not it exhibits the same effect.

Edit, just saw the Sportcenter highlights and it is stutter free, must be a local issue for me and a few other posters on here.

Charter Cable

ESPN picks up a satellite feed separate from FOX Master Control.

That said, I caught a few minutes of the game (OTA / WTTG-DT / DC) and noticed no stuttering in general. There may have been a slight sense of it on one main camera shot? But I'm not sure about that; it could have been just my eyes or interlacing effects (it was viewed on an SDTV).

Considering the problem seems to happen with multiple cable companies, on more than one 720p channel, the stuttering may have to do with an incompatibility with an encoder at the cable headend.

+1. I guess watching the Panthers' games this year won't be much fun, unless this problem is rectified.

No, but it does look better than anything else I've seen on Fox in a long long time. (Watching OTA in Tampa on WTVT).

How good could it be if it isn't HD?

Yes, I noticed it in the FOX game last night too. It's very annoying. It doesn't happen on the SD feed. I'm watching on Time Warner Cable on FOX 5 WNYW out of NYC.

Which shots specifically? Usually I'm really sensitive to any judder or stuttering.

Syracuse too. It's already happening on tonight's Cowboys game.

To all the people thinking they might have seen it, you will definately know when it happens. Its distracting to the point of being unwatchable.

Looks like every shot to me. It's not constant either, it lasts for a few seconds then stops, then happens again. Almost looks like the screen is shaking.

I am getting the same stuttering on the main field-view camera for the Cowboys-Titans game. I'm on Comcast in New Hampshire. Stinks.

Not seeing anything unusual on WJBK-DT FOX Detroit.

If you are seeing the problem, post the city and call letters of the FOX HD station you are watching, and your provider; OTA, Cable, DBS, Verizon, AT&T.
